美国留学生代写作业:真正的飞机

然而,模型过于“简化”可能会阻碍对知识的搜索。一个孩子可能会把纸飞机看作是代表它的“目标”的模型,也就是一架真正的飞机。纸飞机的基本物理原理与真正的飞机有一些相似之处。例如,在这两种情况下,机翼都是一个重要的因素,因为当机翼切割空气以产生更大的压力时,飞机就会产生“升力”。然而,纸飞机与真正的飞机相比常常让孩子们陷入困惑——一架真正的飞机漂浮的时间更长,纸飞机最终会落地。地图也是“简化”表示的另一个例子,因为它们用某种语义方法在平面上定义地球。地图的创建是为了向地图读者传达信息,因此它们根据读者的意图来表示自己的目标。然而,被称为建模的地图学可能会受到质疑——如果读者缺乏阅读地图的技能,无法找到自己的位置,那么地图不就会阻碍他们对知识的搜索吗?数学模型在几乎所有领域都发挥着重要作用,尤其是在自然科学、工程和人文科学领域。数学模型用数学语言表示一种结构或系统,这种数学语言可以以多种形式存在。这些包括人文科学的统计模型,自然科学的指数增长和工程领域的微分学。数学术语和符号方程是很难理解的,因此模型的理论方面通过图表、图形和图表等可视化表示来加强。

However, models being too ‘simplified’ may hinder the search for knowledge. A child may see a paper-plane as a model that represents its ‘objective’ that is, a real aeroplane. The basic physics of a paper-plane has some similarity to that of real aeroplanes. For example, in both cases, the wings are an important factor as the ‘lifting’ of a plane occurs when the wing slices the air to cause more pressure underneath it. However, paper-planes often lead children into confusion when compared with a real one – an actual aeroplane floats longer and a paper-plane eventually rests to ground. Maps are also another example of ‘simplified’ representations as they define the Earth on a flat surface with some semantic approach. Maps are created in order to communicate information to the map readers and consequently they represent their objectives according to the intentions of the readers. However, cartography being called modelling can be questioned – if the reader lacks map reading skills and is unable to locate himself, won’t maps then hinder the search for knowledge for that individual? Mathematical models play a vital role in almost all kinds of fields, especially those in the natural sciences, engineering and the human sciences. A mathematical model represents a structure or a system using mathematical language which can exist in many different forms. These include statistical models in the human sciences, exponential growth in the natural sciences and differential calculus in engineering fields. Mathematical terminology and symbolic equations are difficult to understand and therefore the theoretical aspect of the models is reinforced by visual representations such as charts, graphs and diagrams.
